Single speed v. 2 speed v. variable speed

[Prav]

So, due to age of current pump and motor (and it's about-to-go bearings), will consider replacing the entire pump.

From a VERY quick look, seems Pentair has the 1½ single speed ($300) and VS (>$800) and since electricity in FL is relatively cheap, I would rather spend less because the VS savings would not be there. What I did not see (again, rushing to get out the door today) was a 2-speed Pentair... Do they have any?

Many thanks,

Yes. We have a 1 HP Pentair Dynamo 2-speed and prior to that a 1.5 HP Pentair 2-speed. The 1 HP was a little harder to find but is more than adequate for our 12.5K pool.

The Pentair Whisperflo WFDS series are all two speed pumps. With the spa, you may want to stick with something close to what you had in terms of HP. The WFDS-6 is a full rated 1 1/2 HP two speed pump and the WFDS-28 is a 2 HP up rated pump which has the same performance as the WFDS-6.
